MAX3812 Multirate SMPTE SD/HD Cable Driver with Selectable Slew Rate

Description

The MAX3812 is a multirate SMPTE cable driver designed to operate at data rates up to 1.485Gbps, driving one or two 75Ω coaxial cables. Two selectable slew rates are provided for compliance to SMPTE 292M, SMPTE 344M, and SMPTE 259M. The MAX3812 is pin compatible with the Gennum GS1528.

The MAX3812 inputs are internally biased and compatible with differential swings of CML, LVPECL, and LVDS. Output voltage swing is adjustable with a single external resistor.

The MAX3812 operates over a 0°C to +85°C temperature range. It typically consumes 106mW with a +3.3V power supply and is available in an 8-pin SO package.
